Photoplethysmography (PPG) has been extensively used for pulse oximetry monitoring in
anaesthesia, perioperative and intensive care. However, some components of PPG signal …

Ensuring and maintaining adequate tissue oxygenation at the microcirculatory level might
be considered the holy grail of optimal hemodynamic patient management. However, in …

Background Intradialytic hypotension is a serious complication during renal replacement
therapy in critically ill patients. Early prediction of intradialytic hypotension could allow …

Background Pulse perfusion index (PI) reflects blood perfusion. It has been reported that PI
can be used to evaluate the effect of nerve block, but currently, it is mainly focused on awake …

Objective We determined whether regional haemodynamics and perfusion index (PI) could
be reliable indicators of a successful sciatic nerve block (SNB). Design Prospective …

Purpose Ultrasound-guided supraclavicular brachial plexus block (SCBPB) is performed by
surgeons for upper limb anesthesia; however, certain patients need additional local …

Methods: Eighty-eight patients were randomised to undergo SCB using an ultrasound (USG)-
guided corner-pocket or intertruncal approach and were compared primarily regarding the …

Study objective: To investigate the efficacy of the perfusion index in assessing block success
in pediatric patients undergoing elective supracondylar fracture repair surgery. Methods: It …

Résumé La photopléthysmographie (PPG) est largement utilisée pour le monitorage de la
saturation sanguine en oxygène, en péri-opératoire, en médecine d'urgence et en …

Background: Regional blockade at the brachial plexus provides effective and reliable
anaesthesia and analgesia for upper extremity surgeries. Success is highly dependent upon …
